Overview
The LT1576IS8-5SYNC#PBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A switch and operates at a switching frequency of 200 kHz. The device accepts an input voltage range from 5 V to 25 V and provides a fixed output voltage of 5 V. It features a shutdown function and operates within a temperature range of -40°C to +125°C. The component utilizes bipolar technology and is housed in an 8-pin SOIC package.
Feature Summary
- Integrates a 1.5A power switch with oscillator and control circuitry
- Fixed 5V output configuration for step-down applications
- Supports shutdown mode for power management
Applications
- Industrial equipment power supplies
- Battery-powered systems requiring regulated 5V rails
- Automotive electronics operating within specified temperature ranges
Procurement Notes
Verify the specific suffix SYNC#PBF against official Analog Devices documentation to confirm automotive qualification status and RoHS compliance. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with current production standards before finalizing procurement.
Selection Notes
Select this component when a fixed 5V output is required from a 5V to 25V input source. The 200kHz frequency allows for compact external component sizing compared to lower-frequency regulators. Consider the 1.5A current limit and thermal performance in the SOIC-8 package for load requirements. Verify that the fixed output voltage meets system needs, as adjustable variants exist within the same family.
Part Context
This part belongs to the LT1576 series of high-efficiency step-down switching regulators. The IS8 designation indicates industrial temperature range and SOIC-8 packaging. The SYNC suffix typically denotes automotive-grade reliability or specific manufacturing lot tracking, while #PBF confirms lead-free composition. It serves as a robust solution for converting higher bus voltages to stable low-voltage rails.
Replacement Considerations
LT1576IS8-5#PBF is a non-synchronous variant within the same series offering identical electrical parameters but without integrated synchronous rectification.
